Security Framework in a Virtual Large-Scale Disk System
Minoru Uehara · 2008
Many enterprises proceed to introduce thin clients for internal control. In a thin client environment, a large capable storage is required. However, such storage is expensive. So, we propose novel storage based on PC data grid, and then we call it VLSD (Very Large-Scale Disk). We developed prototype storage of 70TB using VLSD. In our experience, we found that there are several security issues in VLSD. For example, conventional VLSD allows becoming, wiretap and alteration. In this paper, we propose a security framework for VLSD in order to solve these issues on security. Using, this framework, these issues can be solved. In addition, we evaluate the performance of this security framework.
